FCC ID: SVDJP-78901 Circuit Description The 49.86 MHz crystal oscillator drives the base of Q1 the final/buffer amplifier. The modulation provided by Q2 and Q3. The output of Q1 has the matching network consisting of L1 and R18 that limit the harmonic content and effect the proper coupling of the antenna to the output stage. Antenna, Ground and Power Source The antenna consists of a 16.7 cm long Metal antenna. There is no external ground connection. The ground is only that of the printed circuit board. Electric current is supplied by a 9 Volt (“AG13” button cell x 6) primary battery Operation Descriptions The transmitter is a Voice transmitter operating at 49.86MHz band. The transmitter is powered by a 9V battery (“AG13” size battery x6) and the transmitting frequency is crystal controlled. The operation is achieved by different combinations of form pulse modulating signal on the 49.86 MHz carrier frequency. Remarks: The transmitter is a 1 Button transmitter. The EUT continues to transmit while Button is being pressed. It is Voice transmitter, Modulation by Microphone; and type is Amplitude modulation.
